mui's smart home skill enables you to turn off/on your mui board touch display. Phrases like, "Alexa, turn mui board on" activate the mui display screen without requiring a touch interaction. This skill is useful for when the mui board can't be reached, yet needs to be activated. Turning off the mui display is equally useful: you can hide active timers and other information with an 'off' command.
In order to link the mui skill with your mui boards, you need to have previously activated and linked the mui board to the mui app. Setup instructions can be found in mui's Zendesk online quick setup guide. Linking Alexa with mui is easy, just download the skill and login in to your mui account when prompted. Once account linking is finished, you will be able to use the Alexa smart home commands on your mui board.
